Private Iron Blood Test – Fast Answers to Fatigue, Low Energy & Hair Loss
If you’re constantly tired, struggling with low motivation, breathlessness, or unexplained hair thinning, low iron could be the cause — even if you eat well or have had “normal” NHS bloods in the past.
At Holden’s Wellness Clinic (Doncaster & Newark), we offer fast, accurate private Iron & Ferritin Blood Tests — with results in 24–48 hours and no GP referral needed.

- Transferrin Saturation %

Turnaround: 24–48 hours

✔ Why a Private Iron Test Matters (Even If You Think You’re Healthy)
Most people with low iron don’t realise it. Iron deficiency is extremely common — even in people who:
- eat a balanced diet
- go to the gym
- take multivitamins
- have had “normal” NHS bloods
The symptoms creep in slowly — tiredness, brain fog, low mood, breathlessness, poor exercise tolerance — and you often blame stress or ageing.
✔ NHS Often Misses Early Iron Problems
The NHS usually checks only haemoglobin — which stays normal even when your iron stores (ferritin) are already very low.
This means you can be told:
“Your bloods are normal.”
…while still suffering from early iron deficiency.
Ferritin can be depleted for months or even years before anaemia appears.
Our private test includes the full panel the NHS only performs when you’re already severely unwell.
✔ Hidden Causes of Low Iron (Most People Don’t Realise These)
You can have a good diet… and still absorb almost no iron. These common lifestyle and biological factors reduce iron dramatically:
- Stress & inflammation – raises hepcidin, blocking absorption
- Heavy periods – #1 cause in women (often underestimated)
- High tea or coffee intake – tannins reduce absorption by up to 60%
- Grains & soya diet – phytates bind iron
- Gym & endurance training – increases iron demand
- Reflux medication – reduces stomach acid → poor absorption
- Vegetarian/vegan diet – plant iron absorbs at only ~5%
- IBS, coeliac, gut inflammation – reduces uptake
- Pregnancy/postpartum – rapid iron depletion
This is why symptoms often appear even in people who “eat well”.
Symptoms of Low Iron
- Constant tiredness or exhaustion
- Hair thinning or hair loss
- Shortness of breath
- Heart palpitations
- Pale skin
- Feeling cold all the time
- Poor concentration / brain fog
- Craving ice (pica)
If you recognise even 2–3 of these, an iron test is strongly recommended.

Iron & Ferritin Blood Test – FAQs
Do I need to fast before an iron test?
No. Fasting is not usually required for iron or ferritin testing. You can eat and drink as normal unless your clinician advises otherwise.
What is the difference between iron and ferritin?
-
Iron measures the amount of iron currently circulating in your blood.
-
Ferritin shows how much iron your body has stored.
Ferritin is often more useful for identifying early or hidden iron deficiency.
What symptoms can low iron cause?
Low iron or ferritin levels may cause:
-
Ongoing tiredness or low energy
-
Breathlessness on exertion
-
Brain fog or poor concentration
-
Headaches or dizziness
-
Cold hands and feet
Some people have low iron before symptoms become obvious.
Can iron levels be low even if my haemoglobin is normal?
Yes. It’s common to have low ferritin with a normal haemoglobin, especially in women. This can still cause fatigue and reduced performance.
